OK, I've just purchased a new CPU, an AMD 64 3500+ S939, & Mobo, an Asus A8V Deluxe. All of the rest of my setup is the same as below.

So far I've connected the CPU (obviously), HD, DVD drives, floppy drive, graphics card, RAM and all fans. Motherboard's LED light is green to go, and all fans are spinning...

The problem is I'm not getting any video. Just a black screen when I boot up. One long "Beeeeep" comes from the Mobo's speaker (not sure whet exactly this means, other than it's an error of some sort).
